West Brom's latest injury blow as Carlos Corberan reacts to Middlesbrough defeat

Diangana missed out of Tuesday night's home defeat to Middlesbrough, where the visitors ran out 1-0 winners at The Hawthorns.

The versatile attacker picked up a shoulder injury late on in the previous game, Saturday's defeat at Sheffield Wednesday – the other shoulder to the one he injured at Stoke in August.

Diangana missed much of pre-season with a calf problem and injuries to both shoulders have set him back as he looks to make inroads on Corberan's starting line-up. Diangana had caught the eye with his cameo at Hillsborough, where he was involved in Josh Maja's goal. He is a doubt to feature against Millwall on Saturday, prior to the international break.

Summer recruit Gianluca Frabotta, the Italian left-back, also missed out of the squad against Boro and Corberan confirmed that was his selection decision.

"Frabotta has been my decision to put Styles in the squad today and Grady unfortunately suffered a foul where he had a problem with the shoulder. He couldn't be ready to compete," said Corberan.

"It is in the other shoulder. Unfortunately in the beginning he had the problem with the calf, then one shoulder and now the other one and he couldn't get his normal rhythm.

"It looks like it is less serious than the serious one but he is still a doubt for Saturday.

"Exactly (having bad luck), the fact he didn't make a pre-season and after he has come back and suffered a couple of injuries mean he hasn't been ready to help the team in the level we want him to.

"We know he's an important player, without any doubt, we need everyone fit and in the best level."

The result against Boro paled into insignificance as Albion paid tribute to supporter Mark Townsend, 57, who died after the medical emergency in Saturday's game in Sheffield.

Mark, who was a Birmingham Road season ticket holder from Oldbury, was fittingly honoured with a minute's applause in the 57th minute. All players and officials also took part, as did Boro fans. Players wore black armbands and a Townsend 57 shirt was laid on Mark's seat.

Corberan added of the emotional tribute: "We were completely saddened when we lost one of the members of the West Bromwich Albion family. So it was important to show a tribute to him and support to the family in the way that we can do it."

Boro midfielder Hayden Hackney proved the match-winner 17 minutes from time when he stroked home a nice finish from the edge of the box. The visitors could have had more but for a string of fine Alex Palmer saves.

Albion's big chances came once in either half, for Jed Wallace – on his first start of the season – at 0-0 and then top scorer Maja's chance to equalise late on.

"I think in general in the middle of the pitch they were a little bit better than us, and in the last third too," said the head coach.

"I think that both teams arrived enough times in the last third of the pitch and they stretched us more and found a way to make the chances and we didn't find the way to create the same danger as them.

"It is important for us to improve this. We didn't find the clear chances, or the right way to finish the attacks. I believe in the quality of my players but we need to do better because when you don't win the game you didn't do enough good things.

"We didn't compete well enough in general against Sheffield and we didn't finish attacks well enough today. In both games we were close to drawing but in both games we lost. We need to analyse and focus to do the things we didn't do that didn't allow us to win."
